From 40d53f4a60c9eb10d4fa58066c23ba1af8a59e39 Mon Sep 17 00:00:00 2001 From: Andrei Otcheretianski Date: Thu, 4 Jan 2018 17:39:08 +0200 Subject: iwlwifi: mvm: Fix channel switch for count 0 and 1 It was assumed that apply_time==0 implies immediate scheduling, which is wrong. Instead, the fw expects the START_IMMEDIATELY flag to be set. Otherwise, this resulted in 0x3063 assert. Fix that. While at it rename the T2_V2_START_IMMEDIATELY to TE_V2_START_IMMEDIATELY.
